With previous Sony SLTs and NEX cameras I didn't have as much of a problem with hitting record to stop and start the limit again as I did with the cameras overheating after 30-45 minutes in 100+ degree temps.

When I asked the Sony guy at NAB if the $1699 price rumor was accurate he practically scoffed at me. Then he made a comment about how the only other 4k full chip camera was the Canon 1d for $10,000 and that the A7s would not be $1699.

That Sony guy forgot to mention that for the a7s salesprice you don't get 4K but need to buy a ext recorder as well :) Looking at the prizes of the other A7 camera's now I also would doubt it will be around that prize, don't think they will try to compete with the gh4 but rather the 5dIII

Just wanted to address some comments made earlier in this thread about resolution and frame rate.

It's not uncommon to do line skipping for higher frame rates because there is a limitation on how fast you can read out the entire sensor without frying it. The rest of the electronics have to keep up as well and it makes more sense from a design and cost standpoint to offer the higher frame rate by dropping the resolution. You can see this in a lot of cameras on the market.

Even my PDW-F350 shoulder camera did this. Anything over cranked above 30P dropped the vertical resolution from 1080 to 540. To a discerning eye, this might be visible, but the end viewer is likely to never notice.

Did you mention the GH4? Even if it is not FF. Are they trying to pretend it has not changed the 4K price structure?

Sony is awfully quite about their a7s price, they do have some serious competition to consider as their camera can only do 4k with another expensive investment, since 4k is the buzz word right now with many low prized serious offers pricing the a7s too high might kill their sales. Last year I saw a Dutch store giving the XLR-K1M 800 dollar xlr add on for free if you bought the vg900, that's something you don't do if sales go well so they still might be thinking where to place this a7s on their price scale compared to the competitors or they might be giving a 4k recorder with it for free if sales turn out to be bad :) Just look at what BMD did when they trashed their prices just to stay competitive, Sony could very well surprise us with a price they don't want to charge but have no other option to do so.

The way he said it sounded like the GH4 could not even be compared to the A7s. I guess because of the full chip and the supposed amazing low light performance. I do find the low light possibilities exciting but the external recorder for 4k not so much.
